I never liked Voyager's "moral" episodes because they always ended with Janeway avoiding the hard decision and just flying away. DS9 had some great episodes that really tackled the "what's right isn't always what's in the rulebook" angle and they had to actually handle the tough choices.
Data learned that lesson when he decided that he needed to destroy decades worth of work in a colony to convince the colonists to leave.

Voyager just always felt like they had easy outs.

Bow ties are coool.
